If you have a drop-down menu and a YouTube video near the top of your page, you may notice that the video stays on top of the menu items. This is a common problem with certain browsers that present Flash items on top of drop-down menus (and everything else). It is possible to resolve this with a simple addition to the embed code that you copied from YouTube to publish the video to your site.
Below is an example of embedding code. The items in bold need to be added to your YouTube code in order for it to display correctly.
